abstract = {When designing a new large experimental device,
extrapolation from current knowledge and scaling laws into
unexplored design space is unavoidable, and predicting the
behaviour of a new device is therefore subject to
significant uncertainties. This makes it difficult to
determine an optimal design. For conceptual fusion power
plants, a further concern is whether the expected
performance will yield any net electricity and for pulsed
power plants a reasonable pulse length.In this work, we
focus on evaluating the effects of selected uncertainties
regarding the general plasma physics performance in the
current European pulsed DEMO design (nominally 500 MW net
electrical power, 2 h pulse length). This is meant as a
first step towards uncertainty quantification for DEMO. We
use a Monte-Carlo method in combination with the systems
modelling code PROCESS to map out the probable machine
performance. The results show that assuming only these
specific uncertainties it is a reasonable assumption that
the current design is capable of providing 400 MW of net
electricity while maintaining a pulse length of 1 h or
more.},
